Accessing Controls thrue the ID

Question

Hi guys i have a problem ... I started to create a webform with lots of Button and TextBoxes on it. Now i have an array with some int values (Color-Values) and i try to change the colors of the buttons and textboxes. I know how i can change the color-property for one button i named but i would do it automatically. All Buttons have the ID signal + number I remember VB or VBA ... there i could use Me.Controls(signal+i).BackColor = Value //for example I'm looking for an equal command in C# ---------------------------------------------------- for (int intI=0;intI<Num;intI++) { ????? (signal + i).BackColor = Color.(ColorValue[i]); } -------------------------------------------------------- Hope you know what i mean. Thanks for any ideas!!! homer

Control myControl1 = FindControl(signal + i); myControl1.BackColor = Color; Normally the C# commands are the same as VB just a little different in syntax.

Hi Homer You will have to parse your control to access its value like following ((Button)FindControl(signal + number)).BackColor = Color.Red; Hope this helps.

Thx for your reply Ken maybe the way i explained it was not the right one ... First of all the idea is not bad but the main point i'm searching for isn't solved. I tried to set the BackgroundColor of (for example) 10 Buttons. These Buttons named signal1signal2...signal10. Ok i can solve it and can set the BackgroundColor for each button manually ... (signal1.BackColor = Color.Red ... ) but because of i have over 100 buttons i would do it automatically. So i tried serveral combinations of this.Controls(.BackColor) Page.FindControl(.BackColor)myobj.ID(.BackColor) ... but i couldn't find a way to get this BackColor - property after the . (shown in the Listbox which opens after .) i'm searching for an command which is equal to the vb command Me.Controls(signal + number).BackColor = Color; Hope that you now can follow my thoughts ... sorry for bad explanation at the first time. Any ideas are welcome. Thank you very much!!! homer
